Spauligodon carbonelli n. sp. (Nematoda: Pharyngodonidae), a parasite from the caecum of the common wall lizard Podarcis muralis (Laurenti, 1768) and the Spanish wall lizard Podarcis hispanica (Steindachner, 1870) (Reptilia: Lacertidae) in the Pirineos Mountains, Spain, is described. S. carbonelli differs from the other known species of the same genus, mainly in the presence and length of the spicule, the morphology of the caudal end in the male and in the structure of the cephalic end of the female.
